Question

Mick paid $2.94 in sales tax on an item that cost $42.00 before tax. At that rate, how much would he pay in slaes tax for an item that costs $58.00 before tax?

Answer 1

For an item that cost $ 42, Mick paid $2.94 in sales tax. So percentage of sales tax is

$\frac{2.94}{42} *100 = 7%$

And we have to find the sales tax that he paid for an item that cost $58, and for that , we have to find 7% of 58 , that is

$= \frac{7}{100} *58 = 4.06$

So he pays a sales tax of $4.06 .

Answer 2

294/4200=n/5800
4200n=1705200
n=$4.06 sales tax
